# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

$rsa = New-Object Chilkat.Rsa

# Generate a 2048-bit key.  Chilkat RSA supports
# key sizes ranging from 512 bits to 8192 bits.
$privKey = New-Object Chilkat.PrivateKey
$success = $rsa.GenKey(2048,$privKey)

$pubKey = New-Object Chilkat.PublicKey
$privKey.ToPublicKey($pubKey)

# Save the private key in PEM format:
$success = $privKey.SavePemFile("privateKey.pem")
if ($success -eq $false) {
    $($privKey.LastErrorText)
    exit
}

# Save the public key in PEM format:
